Wrist snapping, popping

For a while I'm experiencing something weird about my left wrist, thumb side.
When I wake up at night or after some period of not using my left wrist it feels stiff and when I put weight on it (like when getting up from sitting in bed) there's sharp pain at the base of the thumb/below thumb. And usually accompanied by loud snapping/popping sound. Few nights ago I got up from my bed and didn't notice the stiffness and when I put weight on wrist it make a really loud sound and there was sharp pain as well.
Sometimes it happens in right wrist too but not that much, mostly small pop without any pain, or it (stiffness) pass with movement.

I wonder if it's somehow connected to fall onto my wrist (about two years ago). I slipped on ice and fell backwards on my wrist (left). It barely hurt and there was only minor tenderness and even less pain around thumb base area.
Could there be some connection?
